Vivaldi choosing TTF webfonts instead of WOFF2

Hi,
for some reason, Vivaldi seems to be preferring TTF version of webfonts instead of WOFF2 like other Blink based browsers seem to do, which leads to it displaying quite a few websites with corrupted/substituted fonts for extended characters.

For example, this is one of the URLs for webfonts in the CSSS of Google Trends page:

If you click on this URL in pretty much any other browser I can get my hands on, it fetches an extensive WOFF2 list of font definitions. If you do the same in Vivaldi, it just fetches a basic list of TTF fonts which lack many of the alternatives with extended charsets.

The result is that the page looks pretty bad in Vivaldi, with certain accented characters being shown in completely different font:
